Palmdale Schools On 'Modified Lockdown' After Facebook Threats

PALMDALE (CBSLA.com)—  Schools in the Palmdale area were placed on "modified lockdown" Tuesday after threats were made on Facebook against a group of elementary school children.

An 11-year-old student who attends Joshua Hills Elementary School reportedly received threats on the social networking site for the past month and finally reported them to the Palmdale Sheriff's Station on Monday.

Capt. Bobby Denham said officials don't believe the threats, which involved a sixth grade class at Joshua Hills, are credible.

"We're not sure exactly who made the threat and that's what worried us," he said. "Because the individual's identity was concealed on the Facebook page. But the threat was made specifically toward a group of kids at a class in that school, and that's about the sixth-grade level."

Detectives told Palmdale school officials to put all campuses on controlled access until Friday, which means unauthorized individuals won't be able to enter school grounds.
